I have content loading dynamically (using new WP_query loop in WordPress) for a jQuery carousel or image-scroll function -- where the image-scroll is a li list of images, styled to look like a strip of images.
When the image-scroll works properly, one of the images in the li tag has a class of active, which expands the image and makes it look like it's in front of the other images,
... and as the user clicks through this strip of images, the active class changes/moves to the targeted li tag, expanding that image.
What's happening is that none of the li tags are active when the page loads - since the content is dynamic through the WP loop (I didn't want all of the li tags to start with the active class, so I didn't add it to the loop),
...and so the images are just lined up in a consistent strip w/o one of the images being expanded (or having that active class).
It is only if the user happens to click on one of the images that it expands,
...but i need one of the images to be expanded (to have the class of active) before the user clicks so I need the active class added as/after the page loads.
I have tried through the jQuery code to target one of the li tags to add the active class, using filter() or closest() after the page loads, but that didn't work.
Or maybe I should write a new script to add the active class?
Any help much appreciated!
I have the abbreviated html and the jQuery function below.
_Cindy
ps as the code indicates, I also have corresponding article titles that scroll with the images, so perhaps I need to adjust the jQuery there, too.
<div class="articles-scroll">
<ul class="images-scroll">
<li><!-- I need only one of these tags to have a class of active to start -->
<a href="#">
<span class="set-image-border" style="float: none;">
<img class="setborder" src="image-set-by-new-wp_query">
</span>
</a>
</li>
<li>
<a href="#">
<span class="set-image-border">
<img class="setborder" src="image-set-by-new-wp_query">
</span>
</a>
</li>
</ul>
<div class="clear-float"></div>
<!-- in this section of html one of the article titles is active to coordinate with the active li image above to produce a corresponding clickable title, this works, but once again, only when user clicks on an image to begin the jQuery image-scroll function -->
<div class="wrapper">
<ul class="images-content">
<li>
<div class="article-header">
<h2>
<a href="link-set-by-new-wp_query">
</h2>
</div>
</div>
</li>
<li>
<div class="wrapper">
<div class="article-header">
<h2>
<a href="link-set-by-new-wp_query">
</h2>
</div>
</div>
</li>
</ul>
</div>
jQuery(".images-scroll li a").click(function() {
jQuery(this).parent().parent().find("li").removeClass("active");
// tried the following instruction as well as on next line, but no go
// jQuery(this).parent().parent().closest("li").addClass("active");
jQuery(this).parent().addClass("active");
jQuery(this).parent().parent().parent().find(".images-content > li").removeClass("active");
jQuery(this).parent().parent().parent().find(".images-content > li").eq(jQuery(this).parent().index()).addClass("active");
var step = ((-250)*(jQuery(this).parent().index()-1))-60;
//alert(step);
jQuery(this).parent().parent().css("margin-left", step+"px");
return false;
});
The reason why the code you wrote didn't work is that you have it inside a click handler, so nothing happens until you click one of the targeted elements. If you want something to happen on page load you can use $(document).ready() (can be shortened as $()) or $(window).load(). Just add the following lines below or above your existing code.
jQuery(function(){
var $listItems = jQuery('.images-scroll li');
$listItems.first().addClass('active');
// Second list item
$listItems.eq(1).addClass('active');
// Third list item
$listItems.eq(2).addClass('active');
});
Also, please note that (unless it conflicts with a different plugin), writing $ is shorter than jQuery, and it should do the same.

I have 3 files:
mainPage.html
starter.html
Landing.js
When I click on the div in starter.html I want to move to mainPage.html and then to the Menu section of this page
starter.html code:
<li> <div onclick="onBackToMenu()">Back to menu</div></li>
landing.js code:
function onBackToMenu() {
window.location.href = "../mainPage.html";
document.getElementById("Menu").scrollIntoView();
}
mainPage.html: (partial code)
<!-- Menu section -->
<span class="anchor-offset" id="Menu"></span>
<div class ="section" >
<div class ="sectionHeadings">
<h1>Menu/Products</h1>
<div class="menu">
<div class="starter" onclick="location.href='pages/starter.html';">
<h3 class="menu-heading starter-heading">Starters</h3>
</div>
When I click on the div then it does take me to mainPage.html, but it doesnt want to take me to the Menu section with id of Menu.
Please help
Since you have an id on that section already ==> <span class="anchor-offset" id="Menu"></span> pass the id at the end of your href like this: window.location.href = "../mainPage.html#Menu"; this will a direct you to that section when the new page loads.
function onBackToMenu() {
window.location.href = "../mainPage.html#Menu";
document.getElementById("Menu").scrollIntoView();
}
No javascript is necessary. It's better practice and better for accessibility to use an anchor element (<a>) with an href element to create a hyperlink to the new page with a fragment identifier for the section you want to scroll to.
In your case, just change the list item in starter.html to:
<li>Back to menu</li>
This will navigate a user to the menu section of the new page.
I've created a webpage that has the following structure:
Main html that uses a side menu;
Secondary html that has the information that I want to show in the main html.
I want to achieve the following. Let's say that the secondary html has a section named intro. I want to link that section to a menu item. So when I press the corresponding button, I want to show in my main html the secondary html starting at the #intro section.
This is my sidebar nav in the main html
<div id="main">
<div class="wrapper">
<!-- LEFT SIDEBAR NAV-->
<aside id="left-sidebar-nav">
<ul id="slide-out" class="side-nav leftside-navigation">
<li class="no-padding">
<ul class="collapsible collapsible-accordion">
<li class="bold"><a class="collapsible-header waves-effect waves-blue active"><i class="mdi-action-view-carousel"></i> Field</a>
<div class="collapsible-body">
<ul>
<li class="active">Intro
</li>
</ul>
</div>
</li>
</ul>
</li>
</aside>
</div>
This is the section in the 2nd html.
<div class="divider"></div>
<div class="section" id="intro">
<li style="list-style: disc">
some text.
</li>
</div>
</div>
When I press the Intro button in the left side nav, I want to open in my main html the 2nd one at the Intro section.
The reason I want to load the 2nd html in my main one is that It uses different css styles and It ruins my formatting if I merge them.
Any solution?
Thank you!
It can be easily achieved with jQuery:
Here's my suggestion:
Step 1
First of all, make sure you have those sections in your secondary.html file:
<div id="intro">Intro section</div>
<div id="section1">Section 1</div>
<div id="section2">Section 2</div>
<div id="section3">Section 3</div>
An, in main.html, make sure you have an element with id=content. This will be your placeholder. Like this:
<div id="content"></div>
Step 2
Modify your anchors:
point href to a dummy url (#).
add a class so we can catch this with jQuery. I named here btn-load-section.
add data- attributes so we can add some useful data to each anchor, to grab it later. I added here data-url and data-section.
Like this:
<li>Intro
<li>Section 1
<li>Section 2
<li>Section 3
Step 3
At the end of our <body> section (in main.html), you can add this code:
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<script>
/*
Executes the script inside the anonymous function
only when the page is loaded
*/
$(document).ready(function() {
/*
select all anchors with 'btn-load-section' class (class = dot before)
and bind a click event
*/
$("a.btn-load-section").on("click", function(e) {
e.preventDefault(); //this cancel the original event: the browser stops here
var url = $(this).data('url'); //get the data-url attribute from the anchor
var section = $(this).data('section'); //get the data-section attribute from the anchor
var contentDiv = $("#content"); //select the div with the ID=content (id = hash before). This will be our target div.
/*
executes the jQuery .load function
It will load the url and search for the correspondent section (load page fragment)
e.g. will call load with "secondary.html #intro" (#intro is our fragment on the secondary.html page).
*/
contentDiv.load(url + " #" + section);
});
});
</script>
As I don't know how familiar you're with jQuery, I added some comments.
The first script tag loads jQuery from a CDN.
You can read more about the jQuery's .load function here. But basically it allows to load page fragments:
The .load() method, unlike $.get(), allows us to specify a portion of
the remote document to be inserted. This is achieved with a special
syntax for the url parameter. If one or more space characters are
included in the string, the portion of the string following the first
space is assumed to be a jQuery selector that determines the content
to be loaded.
This is just a possible approach. Hope it helps!
I am using ASP.net and have a master page that utilizes navigation. My problem is when I click on a link it loads a different asp page, but the navigation tab doesn't switch to the clicked color,it reverts back to its original color. Since all the pages are loading the same, I can't just use CSS because the page is reloaded. Is there a way to write a javascript function that tells the page when it loads to display the hover color and keep it there? Since the only HTML I use is on the master page, I can't switch anything out. I'm sure there must be a way using nth-child but I can't figure it out. As for the code, a simple example is:
<div>
<ul>
<li>One</li>
<li>Two</li>
<li>Three</li>
</ul>
</div>
So how would I get the 2nd link to switch to the hover color when loading the page?
It's been a while since I've played with asp, so I won't have the exact terms, but I can point you in the right direction.
First, in your master page, add unique ids to all of your nav links. This will make it trivial to access those links in your specific asp pages. It helps to do this because otherwise it's hard to select the link you want. jQuery such as $("div ul li:nth-child('2')") will select the second li that's a child of a ul that's a child of div, but that could happen anywhere on your page.
Once you have that, let's assume your nav panel looks like this:
<div>
<ul>
<li id="linkOne">One</li>
<li id="linkTwo">Two</li>
<li id="linkThree">Three</li>
</ul>
</div>
Then, in the page that loads when Two is clicked, you need to add a script with an onLoad handler that modifies the link:
<script>
document.onload = function() { $("#linkTwo").addClass("hover"); };
</script>
This will wait till the document loads (otherwise you may try changing an element that doesn't exist yet), then run a function that finds the specific element with the id "linkTwo" and adds the css class "hover" to it.
Obviously, this line will be different for each specific asp page - or something you can have your server-side logic calculate.
Your question is a little unclear. But if i understood right in your case i should use a specific css class that is loaded if you determine that you are on current page.
Something like this (i don't know asp, i will put a general example)
<div>
<ul>
<li <?php if($CurrentPage = 'One') {echo 'class="active"';} ?>>One</li>
<li <?php if($CurrentPage = 'Two') {echo 'class="active"';} ?> >Two</li>
<li <?php if($CurrentPage = 'Three') {echo 'class="active"';} ?>>Three</li>
</ul>
</div>
this will put a special class to your element. That class will have the hover color, and the problem is solved.
Hope you can adapt this to asp.
Use the following:
html code
<body>
<div>
<ul style="display:inline; background-color:lightgray; float:left">
<li style="margin:20px; display:inline-block" onclick="frames['target'].location.href='one.html'; toggle_bgcolor(this);">One</li>
<li style="margin:20px; display:inline-block" onclick="frames['target'].location.href='two.html'; toggle_bgcolor(this);">Two</li>
<li style="margin:20px; display:inline-block" onclick="frames['target'].location.href='three.html'; toggle_bgcolor(this);">Three</li>
</ul>
<iframe id="target"></iframe>
</div>
</body>
JS function
function toggle_bgcolor(elem)
{
for(var c=0; c<elem.parentNode.getElementsByTagName('li').length; c++)
{
elem.parentNode.getElementsByTagName('li')[c].style.backgroundColor='';
}
elem.style.backgroundColor='limegreen';
}
The JS-block for the onclick event in each <li> element will toggle the baclkground-color of each <li> element when another <li> is clicked.

I have 11 elements with long description of each element of them. I decided to display the elements on the sidebar and the description of each one of them will be displayed on the body directly when the user clicks on the element.
I came with a solution similar to this ONE
but the problem with this one is put the content (or description) inside the javascript code, and I want the description be on the HTML code to make it later on flexible for changes by the admin after putting the data including the description of these elements on the database instead of hard-coded style.
Therefore, how can I do that?
You can try this way
<div id="menu">
<ul>
<li id="a">item a
<div id="contentA" style="display:none">Description of item A</div>
</li>
<li id="b">item b
<div id="contentB" style="display:none">Description of item A</div>
</li>
</ul>
</div>
<div id="content"></div>
<script type="text/javascrip">
$(document).ready( function () {
$('#a').click(function() {
$('#content').html($('#contentA').html());
});
$('#b').click(function() {
$('#content').html($('#contentB').html());
});
});
<script>
I updated your example, it now uses hidden divs inside the clickable menu items, and on li click it finds the menu description and displays it.
This method does not depend on ids and degrades more gracefully (except if the client doesn't support JS but supports CSS display).
Your description is a bit unprecise, but if I get it right your could use IDs for the description text and fade them in/out with jQuery.

I am doing a leaderboard for a website we are working on.
Essentially, we have a div with this months winner for location A
Below we have ajax tabs, where user can click tabs which relate to locations, like :
Location A
Location B
etc etc
So by default, when page loads, tab A is open. And the div above we need to give a matching ID, because...
I want as the user clicks tab B for the div above to change, with different DIV ID. So basically we can change content in the div based on the tab the user clicks.
So the content div is like:
<div id="???"> content goes here </div>
The tabs are like:
<ul class="tabs">
<li><span class="stateTab">NSW</span></li>
<li><span class="stateTab">QLD</span></li>
<li><span class="stateTab">VIC</span></li>
<li><span class="stateTab">SA</span></li>
<li><span class="stateTab">WA</span></li>
<li><span class="stateTab">ACT</span></li>
<li><span class="stateTab">NT</span></li>
<li><span class="stateTab">TAS</span></li>
<li><span class="stateTab">AUSTRALIA</span></li>
</ul>
So if user clicks #tab2 then a different DIV loads into the div id="???" .
I think its fairly simple, just cannot figure it out. I realise I possibly have to set all the divs up, like so:
<div id="tab1"> content goes here </div>
<div id="tab2"> content goes here </div>
<div id="tab2"> content goes here </div>
And set visibility hidden to the divs.. any help appreciated.
*** ADDED INFO *******
The tabs, onclick ( presently ) display content from dataTables.
So obviously when we click on tab1, the content below the tabs , shows the content fetched from our dataTables, in a div with id1
The issue now is, with wanting to change the content ABOVE the tabs aswell as the content BELOW the tabs... the 2 id's are conflicting, and one shows and one hides...
The TABS also change content below them, presumably we need to chain the id actions somehow, to get two sets of content to change in harmony
Set it up the way you planned in HTML adding style="display: none" to each div except the one you want to show by default. Then add to you javascript (at the bottom, or in $(function(){ //Document ready });
$('.tabs a').click(function(){
$('div[id^=tab]').hide();
$(this.href).show();
return false;
}
);
As for your Update, you can change your divs to have a class instead of an id. Like
Content Above 1
Content Above 2
Tabs
<div class="tab1 tabContent">Content Below 1</div>
<div class="tab2 tabContent">Content Below 2</div>
Then you can change the javascript:
$('.tabs a').click(function(){
$('div.tabContent').hide();
$('div.'+this.href).show();
return false;
}
);
You'll also need to remove the hashes from your anchors, so the href becomes "tab1" instead of "#tab1"
You could use jQuery to do this: http://jsfiddle.net/YQdQm/
Not sure if this meets your requirements exactly (also, haven't yet tested on IE).
var tabs = $('div[id^=tab]');
tabs.hide();
$('#tab1').show();
$('.tabs a').click(function () {
var tab_id = $(this).attr('href');
tabs.hide();
$(tab_id).show();
});
I would suggest use existing tab control from jquery UI
however if not you will need markup like that
<div class='tabs'>
<ul>
<li data-id='tab1'>tab 1</li>
....
</ul>
<div id='tab1'></div>
<div id='tab2' class='expanded'></div>
...
</div>
and code
$('.tabs ul li').bind('click',function() {
var id = $(this).data('id');
$('.tabs div').removeClass('expanded');
$('#'+id).addClass('expanded');
});
I know this is a bit brute force, but I like to do it this way:
JS:
function hidetabs(){
$("#tab1").hide();
$("#tab2").hide();
//And so on
}
function shobwtab(id){
$("#"+id).show();
hidetabs();
}
HTML:
<li><span class="stateTab">NSW</span></li>
Of course you could also add click listeners in your docready function to run the functions instead of using onClick.
